The City and County of Denver removed and replaced the existing 8th Avenue Bridge over the South Platte River. The 92-year-old bridge had exceeded its design life and needed to be replaced to ensure traveler safety and multimodal mobility. In addition, the existing bridge only accommodated vehicles despite the growing need to accommodate pedestrians and bicyclists.

The $10.8 M project was funded through the Elevate Denver bond program (approved by voters in 2017). This critical project enhanced and modernized the transportation infrastructure in the area by adding a bridge with wider travel lanes, an additional eastbound through travel lane, and multi-use sidewalks on both sides of the bridge. Connections to the South Platte River Trail were enhanced to provide an important regional link for recreation and commuting.

DOTI finalized a new street design that added 1.5 miles of protected bike lanes and almost 2 miles of transit-only lanes along 18th, 19th, and Lincoln Streets.  This project will improve the efficiency of RTD services resulting in faster service with less delays and will support the goals of Vision Zero; to have zero deaths or serious injuries by 2030 regardless of the mode of transportation. 

Design for this project was finalized by December 2020, construction began in the Summer of 2021, and the project was completed in May 2022.

Denver’s Department of Transportation & Infrastructure (DOTI) partnered with the Downtown Denver Partnership (DDP) to bring Colorado’s outdoor culture downtown! 5280 Trail is a five-mile park and urban trail that will circle around Downtown Denver.

This urban trail project will prioritize people, promote healthy lifestyles, and create an outdoor culture with tree-lined places for people of all ages and abilities to walk, roll or bike. It will create a place where a parent can teach their child how to ride a bike or take a stroll with their toddler. A place people can go for a leisurely walk with friends or to unwind on a lunch break.

In 2017, DOTI began analyzing existing conditions and gathering community feedback to identify key locations in downtown for green space, community gardens, public art, and important views. The trail incorporates the community’s feedback as well as neighborhood and city plans to connect vibrant and diverse neighborhoods. Beginning in spring 2021, DOTI re-engaged with the community to create conceptual designs, starting with a 12-block segment of 21st Street.

Both the City and County of Denver (CCD) and the Colorado Department of Transportation (CDOT) recognize the opportunity at the Colfax and Federal Interchange to reevaluate the current configuration and develop a design that maximizes network opportunities and future land use efficiency.

The purpose of the City and County of Denver Colfax and Federal Interchange Transformation Study is to build out the understanding of technical factors, including the interchange configuration, improving the transportation network for all users, stormwater requirements and possibilities, and evaluate the scenarios that best connect to the vision, goals, recommendations and strategies from previous citywide and area specific plans.

The goal of this project was to improve the drainage and mitigate ponding and/or flooding that currently occurs in larger storm events. The Grays Peak General Storm included projects in three locations. Ellsworth Avenue between Steele Street and Garfield Street in Cherry Creek, Wabash / Willow Alley and Sidewalk Improvements in the East Colfax neighborhood and Cedar Avenue and Perry Street in the Barnum neighborhood.

This water quality project along the High Line Canal in southeast Denver included concrete and boulder structures within the Canal to hold and clean stormwater and release it slowly over an extended period of time, and new settling basins and trash vaults to filter out debris on the south side of the Canal.

Background

The purpose of this project was to further address significant historical flooding areas in the Whittier, Five Points and City Park West neighborhoods. This phase of the project connected into the recently completed 33rd Street Outfall project, at the intersection of MLK Jr Boulevard and Marion Street. Future phases will extend this storm sewer infrastructure south to the intersection of 21st Avenue and Downing Street, where it will tie into, and relieve, an overburdened existing 84” storm sewer system. 

General Information

This project installed new 8’ x 8’ Reinforced Concrete Box Culvert in Marion Street to the intersection with 27th Avenue. 

In addition to installing the new 8’ x 8’ storm sewer infrastructure, the Marion Street System project:

• Installed new storm inlets and manholes
• Installed new water quality features to reduce trash/debris from entering into the storm sewer system
• Installed new ADA compliant pedestrian ramps at all intersections
• Upgraded existing curb cuts to be compliant with City of Denver transportation standards
• Relocated and install new Denver Water main lines
• Replaced Denver Water lead service lines with new copper lines from the new water main to the property owners’ meter
• Provided new bike lane at East Whittier Island Park
• Reshaped Marion Street to provide greater surface water storm runoff capacity
• Provided new full depth paving on Marion Street

This project was completed in 2022.

The City and County of Denver is home to nearly 3,000 RTD bus stops used by tens of thousands of bus riders every day to access jobs, healthcare and a variety of other destinations.  Of these nearly 3,000 stops, many are lacking basic infrastructure.  This project, as well as future projects that invest in bus stop infrastructure, will address the current needs systemwide and affirm Denver’s commitment to make the city more accessible for all users.

This project represents a regional partnership between the City and County of Denver, RTD, and the Denver Regional Council of Governments (DRCOG). In 2020, the city received a federal grant for $200,000 through DRCOG and matched it with $150,000 of city capital funds to improve bus stops in Montbello. City planning staff determined the Montbello neighborhood was an ideal area that would benefit most from these improvements due to high ridership and condition of the stops, among other considerations.

Walnut Street in the River North community has a new look and feel to help calm traffic and improve circulation in the area! In conjunction with recent repaving efforts, Denver’s Department of Transportation & Infrastructure (DOTI) converted a stretch of the corridor between Broadway and Downing from one-way to two-way travel. The conversion creates a safer street that reduces vehicle speeds, improves circulation for people walking, biking and driving, and better defines parking and loading zones.

In addition, DOTI has also installed a new traffic signal at the Broadway intersection to help facilitate safer crossings for people walking and riding bikes. Crews converted all parking on this stretch of Walnut Street to parallel parking. An evaluation was also conducted to determine where new traffic control and crosswalks will be placed.

Department of Transportation and Infrastructure (DOTI) studied the East Yale Avenue Corridor from Franklin Street in the west to the High Line Canal trail connection at the city limits, coordinating with the community to explore potential projects along the corridor that would improve conditions for everyone walking, bicycling, taking transit and driving.

The project kicked off in December 2019 and concluded with a community-driven plan in 2022.
